[0051] As shown in FIG. 1, the present invention provides an assist device for using chopsticks having a finger holder 1, a chopstick keeper 2 and an connecting member 3. The finger holder 1 includes two members, and each member is a sleeve 10 to form a hole 11 provided a position for user to put thumb or forefinger in. Each member of the finger holder can has one sleeve 10 (FIG. 1) or two sleeves (FIGS. 7, 8 and 12) for putting fingers thereon. Also, the member of the finger holder can be a windable shaped as shown in FIG. 9. The sleeve 10 has different size for fitting different users. The structure of the finger holder 1 can be closed sleeves 10 as shown in FIGS. 1 and 2, or opened sleeves 10 as shown in FIGS. 7 and 8. The width of the sleeve 10 can be very small as shown in FIGS. 2 and 10. The sleeve 10 and the chopstick keeper 2 are parallel to each other (FIG. 1) or not (FIGS. 2 and 3). Moreover, the finger holder 1 can be in the shape of circle, cone, irregular figure, arch, straight line and hook.

[0052] As shown in FIG. 1, the chopstick keeper 2 includes two parts 20 connected to the two members of the finger holder 1, respectively. Each part of the chopstick keeper 2 includes a position 21, e.g. a through hole, for fixing a chopstick. Moreover, the chopsticks can be directly connected to the finger holder 1.

[0053] The sleeve 10 is rotatable and the angle thereof is capable of being adjusted with respect to the chopstick keeper for properly putting the deformed fingers of a disabled person thereon. As shown in FIG. 4, the sleeve 10 is pivotally connected to a protruding 20 a on the part 20 of the chopstick keeper 2. Thus, the sleeve 10 can be rotated to a proper position for putting user's fingers comfortably. In addition, as shown in FIG. 11, a positioning unit 10 a is disposed on the sleeve 10 in order for rotating and positioning the sleeve 10.

[0054] The connecting member 3 is connected to the two parts 20 of the chopstick keeper 2 such as shown in FIGS. 1, 2 and 3, the two members of the finger holder 1 such as shown in FIG. 5, 7 and 8, in the interconnection of the finger holder 1 such as FIG. 13, or the two chopsticks 4 such as shown in FIG. 6. The connecting member 3 can be U-shaped (FIG. 2), S-shaped (FIG. 11), Z-shaped (FIG. 3), linear-shaped (FIG. 10), M-shaped or W-shaped (FIG. 7), V-shaped (FIG. 8), circle-shaped (FIG. 1), oval-shaped, sphere-shaped (FIG. 6) or other irregular geometric shapes (FIG. 4). The shape of the connecting member 3 is easily pressed to employ the chopsticks to pick things up and has a proper returning force after pressing and returning to the initial position.

[0055] Hence, as shown in FIG. 1, for using the assist device of the present invention, a pair of chopsticks 4 is inserted into the positions 21 of the chopstick keeper 2 and the tips of the chopsticks are passed therethrough. The user can put his thumb and forefinger into the hole 11 of the sleeves 10 of the finger holder 1 for operating the chopsticks 4. Therefore, the user only has to slightly move his fingers, the finger holder 1 will drive the tips of the chopsticks 4 to operate the clipping action. After finishing the clipping action, the returning force of the connecting member 3 will allow the tips of the chopsticks 4 to separate and return to the initial position easily.

[0056] The assist device according to the present invention does keep the chopsticks in a best operating condition even the user cannot use the chopsticks coordinately. That is, the present invention can assure the tips of the chopsticks can pick up food correctly and efficiently even though the finger holder is non-coordinately pressed. Therefore, the present invention provides the assist device for the user who is disabled to use the chopsticks to easily operate the chopsticks for eating. In addition, the chopsticks can be removed from the position 21 of the chopstick keeper 2 for cleaning, so there is no hygiene problem for the present invention.

[0057] Moreover, the finger holder 1, the chopstick keeper 2 and the connecting member 3 can be alternatively assembled. For example, the two parts 20 of the chopstick keeper 2 can be integrally formed with the finger holder 1 and the connecting member 3, respectively. In addition, the chopsticks 4 can be integrally formed with the finger holder 1 or the connecting member 3, e.g. the chopstick keeper 2 is omitted, so the connecting member is connected to the finger holder 1 or the chopsticks 4.

[0058] The relative position between the finger holder 1 and the chopstick keeper 2 or the chopsticks 4 is alternative. That is, the sleeves 10 of the finger holder 1 can be above, below or beside the parts 20 of the chopstick keeper 2 or the chopsticks 4. Furthermore, the sleeves 10 of the finger holder 1 are adjusted in different angles as shown in FIGS. 2 and 3.

[0059] The assist device for using the chopsticks can further includes a guiding member 26 as shown in FIG. 6. The guiding member 26 can be placed in the internal side of the parts 20 of the chopstick keeper 2 such as shown in FIGS. 4, 5 and 12, in the internal side of the chopsticks 4 such as shown in FIG. 6, in the internal side of the connecting member such as shown in FIG. 9, in the internal side or in the interconnection of the finger holder 1 such as shown in FIG. 13. As shown in FIGS. 5 and 6, the guiding member 26 includes two portions 26 a and 26 b which are formed a let-in structure (FIGS. 4, 5, 6, 9 and 13). The two portions of the guiding member can be in a shape of square, triangle, circle, ladder, diamond, flower, lamp or irregular geometric shaped, etc. The guiding member can be placed in one side (FIG. 4) or two sides (FIG. 5, 6, and 13) of the chopstick keeper 2 (FIGS. 4, 5 and 12), the chopsticks 4 (FIG. 6), the connecting member (FIG. 9), the interconnecting area between the chopstick keeper 2 and the finger holder 1 (FIG. 13) or the finger holder 1. Furthermore, the guiding member can be a hollow or solid type. The guiding member is used to prevent the two parts 20 of the chopstick tips from too close or twist owing to improperly pressing. Thus, the guiding member can avoid crossing the tips of the chopsticks and preventing food from falling down.

[0060] In addition, the guiding member 26 can be a guiding groove 27 and a guiding unit 28 as shown in FIG. 12. The user can stably operate the chopstick via the guiding unit 28 sliding in the guiding groove 27 to guide the clipping action. FIG. 13 is an alternative embodiment for the guiding member.

[0061] For increasing the motivation and interest, the assist device can further include an accessory 29 for performing the functions of emitting sound, emitting light, changing shape, changing color or changing size as shown in FIG. 5. Also, the accessory 29 can be connected to any part of the device, with an activating element 29 a for being activated by the connecting member or the guiding member, thereby causing the accessory 29 to perform the functions.

[0062] For fastening the chopsticks in the position of the chopstick keeper 2, the chopstick is fixed by elastic pressing or elastic force. As shown in FIG. 14, the position of the chopstick keeper is a taper-shaped through hole 21 for tightly fastening the chopstick therein. The position of the chopstick keeper is a through hole 21 having at least one elastic element 22 at the inner surface thereof. The position of the chopstick keeper is a through hole 21 having at least one elastic element 22 protruding from the inner surface thereof as shown in FIG. 15 in order to tightly fasten the chopstick therein. As shown in FIG. 16, a leaf spring 23 is established inner of the through hole 21 of the chopstick keeper 2 for fixing the chopstick by the elastic force. In addition, as shown in FIG. 17, the chopstick keeper 2 includes a wedge element 25 movable disposed in the chopstick keeper 2 for fastening the chopstick by screwing. Thus, while the chopstick is placed into the through hole 21, the wedge element 25 can be screwed to tightly press for fastening the chopstick therein.
